I've been using the same shorti put strategy for some time now. I notice that many are going out 9 or even 12 months. I typically go out only 3 months and redo the trade for a fresh 3 months every quarter. Is one way better than the other?
I don't think so; Both work well- for me it's a matter of expected volatility and price vs anticipated events. Longer expiration gives you more premium for fewer shares- so it can be a balance of how many shares you want to be potentially acquiring. I've done both though 3 month and 6month- they seem to work equally well for me. I haven't done a long dated Put though- just don't want to carry the margin that long I guess
